we actually changed people's behaviors by changing their diet. >> so for those people who were hoping for the one or two or three things to stay away from, the one on your list is sugar. >> well, if it's about weight gain, french fries and potato chips are numbers one and two. sugar is actually a distant third, but when we're talking about metabolic syndrome, talking about diabetes, we've shown that the only item in our food supply that actually causes diabetes specifically and not related to its calories and not related to weight gain is sugar. if you consume 150 calories extra per day, your diabetes rate goes up 0.1%. if those 150 calories happen to be a can of soda your diabetes rate goes up 11-fold to 1.1% and we are not consuming 150 calories in sugar. we're consuming 362 so that's a 2.75% increase in diabetes rate. considering our country right now has an 8.3% diabetes prevalence, that is one-third of all of the diabetes in america explained by sugar. >> dr. robert lustig, author of "fat chance" i think you changed some choices this weekend, thank you. >> thank you so much. watc
